Facts (generated by robot; please edit if you find it inaccurate)
- The 5'-3' exonuclease is known to be a structure-specific nuclease that cleaves a 5' displaced strand at the junction between single-stranded and duplex regions.
- Examining the genetic interaction of these two exo1 mutations with rad27Delta suggest that the Exo1p flap-endonuclease activity and not the dsDNA 5'-3' exonuclease is redundant to Rad27p for viability.
- As semiconservative DNA replication is pre- dicted to create a blunt end on the leading strand, a 5'-3' exonuclease is postulated to generate these overhangs.
- The members of this family all appear to possess 5'-3' exonuclease activity EC:3.
- Inactivation of the 5'-3' exonuclease of Thermus aquaticus DNA polymerase.
- Purification and properties of the 5'-3' exonuclease D190-->a mutant of DNA polymerase I from Streptococcus pneumoniae.
